Procedures
==========

Resetting
---------
.. autonim:: bios.SoftReset
.. autonim:: bios.RegisterRamReset

Halting
-------
.. autonim:: bios.Halt
.. autonim:: bios.Stop

.. autonim:: bios.VBlankIntrWait
  
Arithmetic
----------
.. autonim:: bios.Div
.. autonim:: bios.DivArm
.. autonim:: bios.Sqrt

----------------------
.. autonim:: bios.CpuSet
.. autonim:: bios.CpuFastSet

Checksum
--------

Rotation / scaling
------------------

These procedures are misnomers, because :xref:`ObjAffineSet` is merely a special case of :xref:`BgAffineSet`. Results from either can be used for both objs and bgs.

.. autonim:: bios.ObjAffineSet
.. autonim:: bios.BgAffineSet
